Liquid filter bag burst reason
Cause analysis of filter bag bursting:
Pressure problem: the operating pressure should be within the allowable range, the pressure difference should be implemented in accordance with the provisions, there are two ways to see the pressure difference, one is a relatively cheap mechanical pressure gauge, but the error is very large, the other is the flowmeter, the cost is a little higher.
Filter bag itself problem: workmanship problem, filter bag currently do manual work is divided into hot melt welding and line sewing, hot melt welding stress is about 10 kg, and at the bottom of the triangle than arc pressure, seam about 16 kilograms to work under pressure, but if the jump line or off line easy to bag, pressure loss of the filter bag at run time will increase, the impurity scale, very test of the filter bag material and workmanship.
The use of filter bag: the filter bag is not fixed in the filter, and it moves with the rotation of the liquid. In the case of pressure elimination, workmanship and accidents, the polishing degree of the filter basket also determines the use of the filter bag, and improper design of the filter system will also lead to the blasting of the bag.
Accidents and material problems: improper installation of filter bag, improper use by the operator, and defective filter design will lead to the problem of filter bag explosion. In addition, the wrong material choice will even cause damage to the use of filter bag.
